So I paid for these connectors Aug.5th, just got them yesterday Oct 4th. They forgot to mention on their site that your package is drop shipped from China, I don't mind waiting if I know about the wait time. I assumed a couple of weeks, so I started emailing them, all you get is one of three different form replies apologizing and asking for more time. Very frustrating, however the product is very good.
Some 14 ga and 12 ga for the test pieces, using my paint striping hot air gun on Max which is about 800* F
After cooling I mounted them one at a time in the vise an pulled with a pair of ViseGrips, I really had to put my weight into them to get them to break, very good bond, It is the solder that breaks, I could have held the heat to the 12 ga wire longer and got better penetration of the solder.
50 connectors for $23 usd and 8 wks, not too bad,
